Yosemite National Park, United States

One of the first parks in the National Park Service, California's Yosemite is a World Heritage site. Its most
famous scenery includes mountain peaks like Half Dome and El Capitan, Yosemite
Falls, giant sequoias, and sub-alpine lakes. Adventure travel expert Matt
Villano recommends Hetch Hetchy, an uncrowded area in the park’s northwest
corner, for unparalleled hiking.
